Abstract

The invention puts forward a method with verification for intelligently crawling network information in a distributed way. The method comprises the following steps that: when a judgement result shows that the target page data of a website can be obtained after login verification is carried out, obtaining corresponding login information from a database, carrying out automatic login through a browser, and submitting verification information; starting a timed task, using cookie to access the webpage of the timed task, and carrying out keep-alive processing; starting a network package capture detector, accessing a corresponding target page according to business requirements, carrying out HTTP (Hyper Text Transport Protocol) message analysis, carrying out customization on a crawler script, and determining a task crawling data size; and emitting a broadcast by a main node, notifying a corresponding task node, distributing the crawler script, starting the task node, applying for a task from a main node task queue, carrying out data crawling according to the applied task, and storing the crawled target data into the queue so as to store the crawled target data into the database in batches. By use of the method, a protected page can be automatically logged in and accessed, and a quick and expandable distributed webpage crawler integrated framework capable of mining the script is automatically generated.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for crawling network information with verified distributed intelligence. Background technique [0002] Existing components mainly aimed at crawling web pages include the following three methods: [0003] (1) Non-analytic crawler (HTTP-Based): This kind of crawler is based on the HTTP(s) protocol (such as JSoup and HTTPClient in JAVA components), and can construct page requests (HTTPRequest) according to HTTP message rules and connection parameters. ). But this type of crawler does not have a JS engine module, cannot obtain the content dynamically generated by the page, and cannot receive multiple connection pages at a time. [0004] (2) Analytical crawler (Browser-Based): This kind of crawler is also based on the HTTP(s) protocol (such as HtmlUnit in the JAVA component), which can simulate browser behavior, not only accepting multiple connection pages, but also pa...
